JOHN MURPHY, OF AUBURN, NEW YORK.

CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 248,495, dated October 18, 1881.

Application filed October 20, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN MURPHY, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in W'ool and Cotton Garding Machines, of which the following is aful], clear, and exact specification, reference being had to the accompanying drawings, in which Figure lis an endelevation, and Fig. 2, Sheet 2, a plan view, of a so-called finisher carding engine with my improvement attached thereto, together with a diagonal self-feeding device, after the Apperley patent.

Similar letters of reference refer to like parts in the two sheets of drawings.

Oarding-engines as used in the manipulation of woolen stock are arranged in sets of three, known to manufacturers as the first breaker, to which the material is fed as it comes from the picker, the second breaker, to which the material is fed in the form of drawings from the first breaker, and the finisher, to which said material is fed in a similar form from the second breaker.

Much inconvenience and waste of stock has heretofore been occasioned (more especially where self-feeding appliances are used) by the uneven and lumpy nature of the outer threads of roving as they come from the outer rings of the doffer-cylinders of the finisher. This unevenness is causcd by theloopin g, at either side of the feed-table, of the drawing as it is laid back and forth continuously by the automatic feed.

The objectofmyinvention is to conveniently and readily correct this fault by stripping the main cylinder of this uneven stock and passing it back to the feed, so that it maywith it be refed to the finisher, and thus prevent the waste already mentioned.

In the drawings 1 have supposed the engine to be supplied with its full complement ofieedrolls, licker-in, strippers, workers, fancy, doffers, and customary condenser-head.

To effect the object to which I have alluded I make use of what I term a third dofi'er or worker, A, having two rings, 13, of card-clothing, one placed at each end of the same, and of sufficient width to rob or strip from the outer edges of the main cylinderG all of the uneven stock.

Attached to the arches D of the frame E are brackets F, supporting two rolls, G and H, and the vibrating or rub roll J. This roll J is worked backward and forward upon the revolving rolls Gr andHby means of a bell-crank, K, attached to the end of the bracket F, and a link rod or pitman, L, which is actuated by the crank-wheel M, which in turn derives motion through the belt N, passing to the pulley O, which is secured to the main-cylinder shaft P. The roll G derives its rotation from a band, Q, passing to a pulley, R, attached to the shaft of the worker S, and the latter is driven by a band from a pulley on the driving-shaft, the roll H deriving its motion from a band, T, (or

intermediate gearing, if desired,) passing to the end of the roll G. The third dolfer, A, bears upon one end of its shaft a cog-wheel, 2, meshing with a pinion, 3, upon the stripper-shaft e. The latter bearsa pulley, 4, which is driven by the belt 5 from the driving-shaft P, whereby it will be seen that the motion of the drivingshaft is transmitted to the dofier A and stripper-shaft 6, while the worker V is revolved by a belt from a pulley fastened to the shaft of roller A.

In front of the rolls G, H, and J is abail, Y, having a hanger-piece, Z. This bailis secured to two upright standards, (ta, placed on either side of the i'eed table, and carries in its center a twisting-tube, I), which is caused to rotate by means of the band a, passing from a pulley, cl, on the end of the stripper-shaft e, over the idler-pulleysff, to a grooved pulley, g, forming a part of the twister-tube b. In front of the twister-tube b are two short carrying-rolls, h h, supported in the hanger-piece Z, the upper roll being driven by a belt, t', deriving its movement from the feed motion, as shown, or otherwise, as most convenient.

Secured to the ceiling by brackets 1 are the carrier-pulleys j and 7c, the one deriving motion from the other by means of the cross-band Z, and the pulley k driven by a belt from a pulley on the shaft of the stripper S. The pulley j carries the uneven strand of roving and the pulley 7c the drawing as it comes from the second breaker, together with the uneven strand.

The uneven roving is represented by m, the drawing by a, the diagonal feed by 0, and the looped ends of the drawing, as itis fed upon the feed-table in a diagonal form, by 17.

Having thus fully described my invention and its several parts, I will proceed to set forth its operation.

The uneven stock, be it either cotton or wool, upon being taken from the outer edges of the main cylinder by the rings of my third dofl'er or worker, is'passed from these rings'at once between the rolls G and H and the vibrating roller J, where each strand is partially rubbed or felted together, so as to giveit some degree of strength. From thence each strand passes under a guide-finger, q, to the twister-tube b, where the two strands are united or twisted together. From the twister-tube the now single strand passes through the carrying-rolls h h to the carrier-pulley j, from whence it is caused to pass and unite again with the drawing n, to be ret'ed to thefeed-table of the carding-engine, thus causing the fed stock to be more even than if composed of the single di aw ing feed alone.

Itwill thus be seen that the otherwise waste stock is taken from the main cylinder and caused continuously to pass therefrom to the feed'table, avoiding that which has heretofore been of much annoyance and inconvenience to workers of the material, rendering the feed evener and better than primarily given.

Having thus fully set forth myinvention and its operation, what I claim is- 1. The combination, with the dofl'er A and twisting-tube b, arranged substantially as shown, of the intermediate rolls, G H J, and guide-finger q, the roll J having a back-andforth motion over the rolls G H, as and forthe purpose described.

2. In a cardingmachine, the combination, with the dofl'er A, of the rolls G H J, operating together as described, the guide-finger q, the twisting-tube b, the carrying-rolls hh, and the carrier-pulleys j 7;, all arranged substantially as and for the purpose specified.
